Abstract

The aim of the invention is to obtain microwave transponders having a wide range with a small overall height that complies with chip card standards. To this end, the invention involves the use of a film battery. The film battery (40) simultaneously functions as an antenna and is configured as a patch antenna with appropriate dimensions. Alternatively, the film battery (40) can function as a support for a patch antenna (28). The cathode surface (30) of the film battery (40) functions as a large-dimensioned ground surface. It supports an inlet (26) on which a copper lamination is provided in the form of a patch antenna (28) that has a defined length or width (μ/2) according to the provided operating frequency.

Description

Folienbatterie für tragbare Datenträger mit Antennenfunktion Foil battery for portable data carriers with antenna function
Die Erfindung betrifft eine zur Verwendung in tragbaren Datenträgern ausgebildete Folienbatterie sowie einen tragbaren Datenträger mit einem Mikrowellen-Transponder.The invention relates to a foil battery designed for use in portable data carriers and to a portable data carrier with a microwave transponder.
Transponder finden als Bestandteil von kontaktlosen Identifikationssystemen zunehmend Verbreitung, beispielsweise in Wegfahrsperren, Zugangsberechtigungen, bei der Gebührenerhebung etc. In der einfachsten Bauform bestehen Transponder aus einem Chip und einer Antenne. Zum Betreiben des Chips empfängt der Transponder Energie von einem Lesegerät. Für geringe Reichweiten reicht diese Energie zum Betreiben beispielsweise eines Mikroprozessorsystems und zum Zurücksenden von Information von dem Transponder zu dem Lesegerät aus.As part of contactless identification systems, transponders are becoming increasingly widespread, for example in immobilizers, access authorizations, charging fees, etc. In the simplest design, transponders consist of a chip and an antenna. To operate the chip, the transponder receives energy from a reading device. For short ranges, this energy is sufficient to operate a microprocessor system, for example, and to send information back from the transponder to the reader.
Für größere Reichweiten eignen sich Mikrowellen-Transponder, die zum Beispiel bei einer Frequenz von 2,45 GHz arbeiten und eine Reichweite von 1 bis etwa 12 Meter aufweisen.For larger ranges, microwave transponders are suitable, which operate at a frequency of 2.45 GHz, for example, and have a range of 1 to about 12 meters.
Bekannt sind ferner Mikrowellen-Transponder in einer Bauform, deren Grundriß dem von Chipkarten gemäß ISO 7810 entspricht. Vor allem über große Distanzen reicht die von einem Lesegerät abgestrahlte Energie für den Betrieb solcher Transponder aber nicht aus. Transponder im Chipkarten- f ormat besitzen deshalb häufig eine eigene Energieversorgung, üblicherweise in Form einer Knopf Zellenbatterie.Also known are microwave transponders in a design whose layout corresponds to that of chip cards according to ISO 7810. Above all, however, the energy emitted by a reader is not sufficient to operate such transponders over long distances. Transponders in the chip card format therefore often have their own energy supply, usually in the form of a button cell battery.
Figur 3 zeigt einen solchen Transponder 1 in Form einer Chipkarte 2. Länge und Breite der Chipkarte 2 entsprechen der ISO 7810. Das Gehäuse der Chip- karte 3 nimmt zwei Knopfzellenbatterien 4, eine Patch- Antenne 6, einen Mikrochip 8, Anschlüsse 10 sowie einen Quartzschwinger 12 auf. Zwar entspricht der in Figur 3 dargestellte Mikrowellen-Transponder in seinem Grundriß, d.h. in Länge und Breite der Norm ISO 7810, nicht aber in seiner Höhe. Durch die Verwendung der Knopf zellenbatterien 4 wird vielmehr eine relativ große Bauhöhe bedingt. Aufgrund der Dicke der üblichen Knopf zellen läßt sich der in Figur 4 gezeigte Transponder praktisch nicht unter eine Dicke von 5 mm bringen.FIG. 3 shows such a transponder 1 in the form of a chip card 2. The length and width of the chip card 2 correspond to ISO 7810. The housing of the chip card 3 takes two button cell batteries 4, a patch antenna 6, a microchip 8, connections 10 and one Quartz transducer 12. The microwave transponder shown in FIG. 3 corresponds in its layout, ie in length and width, to the ISO 7810 standard, but not in its height. By using the button cell batteries 4 rather a relatively large height is required. Due to the thickness of the usual button cells, the transponder shown in FIG. 4 can practically not be reduced to a thickness of 5 mm.
Angestrebt ist gleichwohl eine chipkartennormgerechte Dicke von 0,8 mm. Für Zwecke, die eine geringe Bauhöhe erfordern ist es hierbei bekannt,Nevertheless, the aim is a thickness of 0.8 mm that complies with the chip card. For purposes that require a low overall height, it is known
Folienbatterien zu verwenden. Das sind Batterien mit einem Metallgehäuse und einem metallischen Deckel, zwischen denen eine Schichtanordnung aus einer Anode, einer Kathode und einem Elektrolyt untergebracht ist. Der Rand zwischen dem Umfang des Elektrolytträgers und den Rändern der Gehäuseteile ist abgedichtet. Die beiden Gehäuseteile besitzen Anschlüsse zum Abnehmen der elektrischen Energie.To use foil batteries. These are batteries with a metal housing and a metal cover, between which a layer arrangement of an anode, a cathode and an electrolyte is housed. The edge between the periphery of the electrolyte carrier and the edges of the housing parts is sealed. The two housing parts have connections for removing the electrical energy.
Solche Folienbatterien lassen sich in flache Karten mit Display und dergleichen einbauen. Jedoch eignen sich auch übliche Folienbatterien nicht für Mikrowellen-Transponder, da sich hier aufgrund der räumlichen Nähe von Antenne und Folienbatterie eine unerwünschte und nicht hinnehmbare Abschirmung der Antenne durch die ein metallisches Gehäuse aufweisende Folienbatterie ergäbe.Such foil batteries can be installed in flat cards with a display and the like. However, conventional foil batteries are also not suitable for microwave transponders, since the spatial proximity of the antenna and the foil battery would result in an undesirable and unacceptable shielding of the antenna by the foil battery having a metallic housing.
Der Erfindung liegt daher die Aufgabe zugrunde, die Verwendung vonThe invention is therefore based on the object of using
Folienbatterien auf Mikrowellen-Transponder auszuweiten. Außerdem soll ein kartenfö miger Mikrowellen-Transponder sowie eine Chipkarte mit einem derartigen Transponder angegeben werden, die eine normgemäße flache Bauweise einer Chipkarte zulassen. Eine erfindungsgemäße Folienbatterie mit einem elektrisch leitfähigen Gehäuse, in dem eine Anode, eine Kathode und ein Elektrolyt untergebracht sind, zeichnet sich dadurch aus, daß der geometrische Grundriß der Folien- batterie einer Antenne, insbesondere einer Planar- oder Patch- Antenne, entsprechend ausgebildet ist.Extend foil batteries to microwave transponders. In addition, a kartenfö-shaped microwave transponder and a chip card with such a transponder are to be specified, which allow a standard flat design of a chip card. A foil battery according to the invention with an electrically conductive housing, in which an anode, a cathode and an electrolyte are accommodated, is characterized in that the geometrical outline of the foil battery of an antenna, in particular a planar or patch antenna, is designed accordingly ,
Zwar läßt sich in Bauteilen wie einer flach zu haltenden Chipkarte aufgrund der großen Abschirmwirkung der Folienbatterie eine Folienbatterie nicht in Verbindung mit einer Antenne einsetzen. Erfindungsgemäß wird jedoch die Folienbatterie selbst als Mikrowellen-Transponder- Antenne ausgebildet. Damit dient die Folienbatterie gleichzeitig zur Spannungsversorgung und als Sende- und Empfangsantenne für die Datenübertragung. Aus der Literatur sind die verschiedensten Aus-gestaltungen von Antennen, insbesondere auch Patch- und Planar- Antennen bekannt. Abhängig von der gewünschten Betriebsfrequenz kann dann eine Planar- Antenne zum Beispiel mit der erforderlichen Länge (λ/2) ausgebildet werden. Die Anschlüsse für die Spannungsversorgung können dann so gelegt werden, daß sie bei einem Spa_nnungsminimum liegen, so daß die Versorgungsspannung frei von HF- Spannung zur Verfügung steht. Möglich ist auch die Zusammenlegung des Anschlußpunkts für die Gleichspan-nungsversorgung und des Antennenanschlusses. In diesem Fall würde das an dem Anschluß abgegriffene Signal mittels einer elektronischen Schaltung, welche von der Folienbatterie versorgt wird, in Gleichstromanteil und Hochfrequenzanteil separiert.In components such as a chip card to be held flat, a foil battery cannot be used in connection with an antenna due to the large shielding effect of the foil battery. According to the invention, however, the foil battery itself is designed as a microwave transponder antenna. The foil battery thus serves both as a power supply and as a transmitting and receiving antenna for data transmission. A wide variety of antenna designs, in particular also patch and planar antennas, are known from the literature. Depending on the desired operating frequency, a planar antenna can then be formed, for example, with the required length (λ / 2). The connections for the voltage supply can then be placed in such a way that they are at a minimum voltage, so that the supply voltage is available free of HF voltage. It is also possible to merge the connection point for the DC voltage supply and the antenna connection. In this case, the signal tapped at the connection would be separated into a direct current component and a high-frequency component by means of an electronic circuit, which is supplied by the foil battery.
In einer alternativen Ausführung der Erfindung besitzt die Folienbatterie einen typischen Aufbaujx t einem elektrisch leitfähigen Gehäuse, in dem eine Anode, eine Kathode sowie ein Elektrolyt untergebracht sind, wobei auf einer Gehäuse- Außenseite eine dielektrischen Schicht angeordnet ist. Auf der dielektrischen Schicht befindet sich nun jedoch noch eine Metallinsbesondere Kupferkaschierung, die als Patch- Antenne dient. Bei einer Betriebsfrequenz von zum Beispiel 2,45 GHz beträgt die Länge der Patch- Antenne dann λ/2 = 6,11 cm. Eine Folienbatterie mit einer solchen Breiten- oder Längenabmessung hat ausreichende Kapazität und läßt sich auch innerhalb des Grundrisses einer normgerechten Chipkarte unterbringen. Durch die Verwendung einer Folienbatterie gleichzeitig zur Spannungsversorgung und als Antenne bleiben die Vorteile eines Mikrowellen-Trans- ponders praktisch unverändert erhalten, das heißt insbesondere eine Reichweite von bis zu circa 12 Meter. Diese große Reichweite macht es möglich, für unterschiedlichste Zwecke vorgesehene Transponder in Chipkartenform zu bringen, die der ISO 7810 entsprechen. Solche Transponder lassen sich für unterschiedlichste Zwecke einsetzen, beispielsweise als Gebührenerhebungsmittel in öffentlichen Verkehrssystemen etc. Ein erfindungsgemäßer kartenförmiger Mikrowellen-Transponder mit einer gleichzeitig als Antenne fungierenden Folienbatterie hat insbesondere die Form einer Chipkarte, da sich hierfür besonders interessante und zahlreiche Anwendungen ergeben. Allerdings ist die erfindungsgemäße Idee nicht auf die Chipkarte beschränkt, sondern die gleichzeitig als Antenne fungierende Folienbatterie läßt sich auch in Mobiltelefonen, Palmtops und anderen Geräten mit genormter Schnittstelle anordnen.In an alternative embodiment of the invention, the foil battery has a typical construction of an electrically conductive housing, in which an anode, a cathode and an electrolyte are accommodated, a dielectric layer being arranged on an outside of the housing. On However, there is still a metal, in particular copper cladding, in the dielectric layer, which serves as a patch antenna. At an operating frequency of 2.45 GHz, for example, the length of the patch antenna is then λ / 2 = 6.11 cm. A foil battery with such a width or length dimension has sufficient capacity and can also be accommodated within the layout of a standard-compliant chip card. By using a foil battery at the same time as the power supply and as an antenna, the advantages of a microwave transponder remain practically unchanged, in particular a range of up to approximately 12 meters. This large range makes it possible to bring transponders in the form of chip cards which are intended for a wide variety of purposes and which comply with ISO 7810. Such transponders can be used for a wide variety of purposes, for example as toll collection means in public transport systems etc. A card-shaped microwave transponder according to the invention with a foil battery that also functions as an antenna has in particular the form of a chip card, since this results in particularly interesting and numerous applications. However, the idea according to the invention is not limited to the chip card, but the foil battery, which also functions as an antenna, can also be arranged in mobile telephones, palmtops and other devices with a standardized interface.

Figur 3 eine Draufsicht auf einen zum Stand zählenden Transponder mit dem Grundriß einer Chipkarte.Figure 3 is a plan view of a transponder belonging to the stand with the outline of a chip card.
Figur 1 zeigt durch gestrichelte Linien angedeutet die Umrisse eines tragbaren Datenträgers in Gestalt einer Chipkarte 20 mit einem Chip 22 und einer Folienbatterie 40. Folienbatterie.40 und Chip 22 sind über nicht dargestellte Anschlüsse verbunden. Bei dieser Ausführungsform dient die Folienbatterie 40 zugleich als großflächige Massefläche für eine Patch- oder Planar- Antenne 28.FIG. 1 shows the outline of a portable data carrier in the form of a chip card 20 with a chip 22 and a foil battery 40, indicated by dashed lines. Foil battery 40 and chip 22 are connected via connections (not shown). In this embodiment, the foil battery 40 also serves as a large-area ground surface for a patch or planar antenna 28.
Die Folienbatterie 40 ist von bekannter Bauart und soll hier deshalb nicht näher erläutert zu werden. Grundsätzlich bestehen Folienbatterien aus einem metallischen Gehäuse mit Gehäuseunterteil und Gehäusedeckel oder - oberteil, wobei in dem Gehäuse eine Anode, eine Kathode und dazwischen ein Elektrolyt in einem Elektrolytträger ausgebildet sind. Anode und Kathode stehen mit dem metallischen Gehäuse in Verbindung, wobei zwischen Ober- und Unterteil des Gehäuses ein isolierendes Dichtungs- material angeordnet ist. Über am Gehäuseoberteil und Gehäuseunterteil befindliche Anschlüsse kann der Batterie Energie entnommen werden.The foil battery 40 is of a known type and will therefore not be explained in more detail here. Basically, foil batteries consist of a metallic housing with lower housing part and housing cover or - upper part, wherein an anode, a cathode and an electrolyte in between are formed in an electrolyte carrier in the housing. The anode and cathode are connected to the metallic housing, an insulating sealing material being arranged between the upper and lower part of the housing. Energy can be drawn from the battery via connections on the top and bottom of the housing.
Die Oberseite der Folienbatterie 40 wird von einer Kathodenfläche 30 gebildet. Auf die Kathodenfläche 30 ist eine Dielektrikumschicht 26 aufgebracht, auf der wiederum eine Metallbeschichtung ausgebildet ist, welche die Form einer Patch- Antenne 28 hat. Die Aufbringung der Dielektrikümschicht 26 und der Metallbeschichtung kann z.B. durch Aufbringen einer kupferkaschierten Inletf olie erfolgen, wobei die Kupferkaschierung die Form und die Größe der Patchantenne 28 aufweist. Die Patchatenne 28 besitzt die Länge λ/2, wobei λ/2 die halbe Wellenlänge der Betriebsfrequenz 28 ist. Um eine optimale Funktion der Patchantenne 28 zu gewährleisten, besitzt die Kathodenfläche 30 eine auf die Patchantenne 28 abgestimmte Größe von wenigstens λ x λ.The top of the foil battery 40 is formed by a cathode surface 30. A dielectric layer 26 is applied to the cathode surface 30, on which in turn a metal coating is formed, which has the shape of a patch antenna 28. The application of the dielectric layer 26 and the metal coating can e.g. by applying a copper-clad inlet film, the copper cladding having the shape and size of the patch antenna 28. The patch antenna 28 has the length λ / 2, where λ / 2 is half the wavelength of the operating frequency 28. In order to ensure optimal functioning of the patch antenna 28, the cathode surface 30 has a size of at least λ x λ that is matched to the patch antenna 28.
Bei der Fertigung einer solchen Antenne 28 muß darauf geachtet werden, daß eine feste, mechanisch stabile Verbindung zwischen der Oberfläche der Folienbatterie und der Inletf olie 26 vorhanden ist, da der Abstand zwischen der Patch- Antenne 28 und der Massefläche, d.h. der Kathodenfläche, 30 die elektrischen Eigenschaften der Anordnung stark beeinflußt.When manufacturing such an antenna 28, care must be taken to ensure that there is a firm, mechanically stable connection between the surface of the foil battery and the insert film 26, since the distance between the patch antenna 28 and the ground surface, i.e. the cathode surface, 30 greatly influences the electrical properties of the arrangement.
Die in Figur 1 in perspektivischer Darstellung gezeigte Folienbatterie 40 besitzt einen üblichen funktionellen Aufbau. Die Kathoden- und Anodenschicht besitzen Anschlußfahnen 32 und 34, an denen die Gleich- Versorgungsspannung für einen an sich beliebigen Chip eines Transponders abgegriffen werden kann. Die Lage der Anschlußfahnen 32, 34 ist grundsätzlich frei wählbar. Bei geeigneter Plazierung an den Gehäuseteilen können die Anschlußfahnen 32, 34 zugleich auch zum Abgreifen bzw. zum Einspeisen einer empfangenen bzw. zu sendenden HF-Spannung verwendet werden. Die dann notwendige Trennung der HF-Signale von derThe film battery 40 shown in a perspective view in FIG. 1 has a customary functional structure. The cathode and anode layer have connection lugs 32 and 34, on which the DC supply voltage for any chip of a transponder can be tapped. The location of the connecting lugs 32, 34 is basically freely selectable. With a suitable placement on the housing parts, the connecting lugs 32, 34 can also be used for tapping or feeding in a received or to be transmitted RF voltage. The then necessary separation of the HF signals from the
Gleichstromversorgung des Chips erfolgt in dem Chip. Alternativ können auch separate Anschlüsse an den Gehäuse-teilen vorgesehen sein. Die geometrische Gestaltung der in Figur 1 gezeigten Folienbatterie 40 gehorcht den Vorgaben der Betriebsfrequenz. Das heißt hier, daß die Länge der Folienbatterie 40 der halben Wellenlänge λ/2 der Betriebsfrequenz entspricht.DC supply of the chip takes place in the chip. Alternatively, separate connections can also be provided on the housing parts. The geometrical design of the foil battery 40 shown in FIG. 1 obeys the requirements of the operating frequency. That means here that the length of the foil battery 40 corresponds to half the wavelength λ / 2 of the operating frequency.
Alternativ zu einer Patchatenne 28 kann mittels einer Folienbatterie 40, wie sie in Fig. 1 dargestellt ist, auch eine Dipolantenne 38 realisiert werden. Die Folienbatterie 28 wird hierzu, wie in Fig. 2 veranschaulicht, aus zwei galvanisch getrennten Teilsegmenten 40A, 40B aufgebaut, die jeweils die Länge λ/4 besitzen und zusammen einen λ/2 - Dipol bilden. Das Aufbringen einer Dielektrikumsschicht 26 oder einer Metallbeschichtung können bei der Dipolvariante entfallen.As an alternative to a patch antenna 28, a dipole antenna 38 can also be implemented by means of a foil battery 40, as shown in FIG. 1. For this purpose, the film battery 28, as illustrated in FIG. 2, is constructed from two galvanically separated sub-segments 40A, 40B, each of which has the length λ / 4 and together form a λ / 2 dipole. The application of a dielectric layer 26 or a metal coating can be omitted in the dipole variant.
Unter Beibehaltung des grundlegenden Gedankens, eine Folienbatterie zugleich als Antenne einzusetzen, gestattet die Erfindung eine Vielzahl weiterer Ausgestaltungen. Besonders gilt dies für die geometrische Gestaltung der Antenne, ihrer Verbindungen zum Chip, für den Aufbau geeigneter Inlettfolien oder für die Gestalt der tragbaren Datenträger in denen die vorgeschlagene Folienbatterie eingesetzt wird. Anstelle einer Folienbatterie 40 bzw. 40 A, 40B kann ferner auch ein anderer Typ von Flachbatterien eingesetzt werden, sofern zumindest eine Oberseite seines Gehäuses elektrisch leitfähig ist. While maintaining the basic idea of using a foil battery as an antenna at the same time, the invention permits a large number of further configurations. This applies in particular to the geometric design of the antenna, its connections to the chip, the construction of suitable ticking foils or the shape of the portable data carriers in which the proposed foil battery is used. Instead of a foil battery 40 or 40 A, 40B, another type of flat battery can also be used, provided that at least one top of its housing is electrically conductive.
